This is the only thing I’ve waited for until now (after watching the cool movie at the E3), and it’s also one of the reasons for me to not get a PS3 yet.
The motion controller is proven to be more sensitive, Wii-like but we are served with much better graphics. Although it still has a controller to hold (unlike Microsoft’s Natal) I agree with Sony that playing games still need to push buttons. The only thing to wait for now is the pricing. If the device has a reasonable price, the launching day will be the day I get mine. 😉
